Some communications over a wireless communication band, for example, aDMG band or any other band, may be performed over a single channelbandwidth (BW). For example, the IEEE 802.11ad Specification defines a60 GHz system with a single channel bandwidth (BW) of 2.16 GHz, which isto be used by all Stations (STAs) for both transmission and reception.

In some demonstrative embodiments, device 102 and/or device 140 may beconfigured to implement one or more mechanisms, which may, for example,enable to extend a single-channel BW scheme, e.g., a scheme inaccordance with the IEEE 802.11ad Specification or any other scheme, forhigher data rates and/or increased capabilities, e.g., as describedbelow.

In some demonstrative embodiments, devices 102 and/or 140 may beconfigured to communicate over a Next Generation 60 GHz (NG60) network,an Extended DMG (EDMG) network, and/or any other network. For example,devices 102 and/or 140 may be configured to use channel bonding, forexample, for communicating over the NG60 and/or EDMG networks.

Some Specifications, e.g., an IEEE 802.11ad Specification, may beconfigured to support a Single User (SU) system, in which a Station(STA) cannot transmit frames to more than a single STA at a time. SuchSpecifications may not be able, for example, to support a STAtransmitting to multiple STAs simultaneously, for example, using amulti-user MIMO (MU-MIMO) scheme, e.g., a downlink (DL) MU-MIMO, or anyother MU scheme.

In some demonstrative embodiments, devices 102 and/or 140 may beconfigured to implement one or more Multi-User (MU) mechanisms. Forexample, devices 102 and/or 140 may be configured to implement one ormore MU mechanisms, which may be configured to enable MU communicationof Downlink (DL) frames using a Multiple-Input-Multiple-Output (MIMO)scheme, for example, between a device, e.g., device 102, and a pluralityof devices, e.g., including device 140 and/or one or more other devices.

In some demonstrative embodiments, devices 102 and/or 140 may beconfigured to communicate over a Next Generation 60 GHz (NG60) network,an Extended DMG (EDMG) network, and/or any other network. For example,devices 102 and/or 140 may be configured to communicate MIMO, e.g., DLMU-MIMO, transmissions and/or use channel bonding, for example, forcommunicating over the NG60 and/or EDMG networks.

In some demonstrative embodiments, devices 102 and/or 140 may include,operate as, and/or perform the functionality of one or more EDMG STAs.For example, device 102 may include, operate as, and/or perform thefunctionality of, at least one EDMG STA, and/or device 140 may include,operate as, and/or perform the functionality of, at least one EDMG STA.

In one example, an EDMG STA may include a DMG STA whose radiotransmitter is capable of transmitting and receiving EDMG physical layer(PHY) protocol data units (PPDUs). The EDMG STA may perform any otheradditional or alternative functionality.

In some demonstrative embodiments, devices 102 and/or 140 may includeEDMG STAs capable of communicating in an EDMG BSS. For example, the EDMGBASS may include a BSS, in which a DMG Beacon frame transmitted by anEDMG STA includes an EDMG Capabilities element, e.g., as describedbelow.

In some demonstrative embodiments, devices 102 and/or 140 may beconfigured to support one or more mechanisms and/or features, forexample, channel bonding, single user (SU) MIMO, and/or and multi user(MU) MIMO, for example, in accordance with an IEEE 802.11ay Standardand/or any other standard and/or protocol.

In some demonstrative embodiments, devices 102 and/or 140 may beconfigured to support the one or more mechanisms and/or features in abackwards compatible manner, e.g., in a manner which may be compatiblewith one or more devices (“legacy devices”), which may not support thesemechanisms and/or features, e.g., one or more non-EDMG stations, forexample, stations configured according to an IEEE 802.11ad Standard, andthe like.

In one example, a legacy station (STA), for example, a DMG STA, mayinclude, may comply with, and/or may be configured according to, a firstspecification, for example, an IEEE 802.11ad Specification, while anon-legacy station (STA), for example, an EDMG STA, may include, maycomply with, and/or may be configured according to, a secondspecification, for example, an IEEE 802.11ay Specification, or any otherSpecification.

In some demonstrative embodiments, devices 102 and/or 140 may beconfigured to be able to communicate in a deployment, scenario, and/orimplementation (“mixed scenario”), which may include both one or morelegacy STAs as well as one or more non-legacy STAs, e.g., as describedbelow.

Reference is made to FIG. 2, which schematically a Basic Service Set(BSS) 200, in accordance with some demonstrative embodiments.

In some demonstrative embodiments, as shown in FIG. 2, BSS 200 mayinclude one or more DMG stations 202, and one or more EDMG stations 204.

In some demonstrative embodiments, devices 102 and/or 140 (FIG. 1) maybe configured to operate as, perform the functionality of, and/orperform one or more operations of EDMG STAs 204.

In some demonstrative embodiments, an EDMG STA 204, e.g., a STAimplemented by device 102 (FIG. 1) and/or a STA implemented by device140 (FIG. 1), may be configured to announce an EDMG capability of EDMGSTA 204, for example, to enable one or more STAs, e.g., one or moreother EDMG STAs 204 in BSS 200, e.g., one or more PCP/AP EDMG STAsand/or one or more non-AP/PCP EDMG STAs, to identify that the EDMG STA204 has EDMG capabilities and/or to differentiate EDMG STA 204 from thenon-EDMG STAs 202.

In some demonstrative embodiments, a first EDMG STA 204 may announce anEDMG capability of the first EDMG STA 204, and/or a second EDMG STA 204may announce an EDMG capability of the second EDMG STA 204. According tothese embodiments, the first EDMG STA 204 may be able to identify thatthe second EDMG STA 204 is an EDMG STA, and/or the second EDMG STA 204may be able to identify that the first EDMG STA 204 is an EDMG STA.According to these embodiments, the first EDMG STA 204 may communicateone or more communications with the second EDMG STA 204 according to oneor more EDMG communications schemes, e.g., using a channel bondingscheme and/or a MU MIMO scheme, e.g., based on the identifying that thatthe second EDMG STA 204 is an EDMG STA; and/or the second EDMG STA 204may communicate one or more communications with the first EDMG STA 204according to one or more EDMG communications schemes, e.g., using achannel bonding scheme and/or a MU MIMO scheme, e.g., based on theidentifying that that the first EDMG STA 204 is an EDMG STA.

In some demonstrative embodiments, it may not be advantageous to definecapability information elements (IEs), which may be carried in beaconand probe frames, wherein a presence or absence of the IEs in the framesmay indicate the support or lack of support for one or more EDMGfeatures, for example, channel bonding, MU MIMO, and/or one or moreadditional or alternative features of the EDMG.

For example, such an approach may face one or more challenges, forexample, if implemented in a DMG scenario, for example, in a mixed BSS,e.g., BSS 200, including one or more DMG STAs 202.

In one example, it may be optional for a station, which is a PCP/AP STA,to transmit the capability IEs in DMG Beacon frames. For example, a DMGBeacon frame may be transmitted at a low Modulation and Coding Scheme(MCS), e.g., MCS0, and through sector sweeping, which may effectivelydecrease a net data rate of the beacon frame, e.g., about 1000 timeslower, than the data rate. Hence, an addition of the capability IEs inDMG Beacon frames may significantly impact protocol efficiency.Therefore, a product implementation may prefer not to include thecapability IEs in DMG Beacon frames.

In another example, it may not be advantageous to include the capabilityIEs in Probe Request and/or Response frames, for example, since theframes may be exchanged only after beamforming (BF) is performed, e.g.,according to an IEEE 802.11ad Specification. Accordingly, a STA wouldfirst have to perform the entire BF training procedure before the STAcan exchange probe frames with the capability IEs. This may lead tohigher power consumption, for example, in cases, when the STA discoversthat the peer STA does not support the required EDMG capabilities afterperforming the BF.

Referring back to FIG. 1, in some demonstrative embodiments, devices 102and/or 140 may be configured to include an indication of an EDMGcapability, for example, an EDMG supported capability attribute, e.g., a1 bit indication, and/or any indication of one or more additional EDMGcapabilities, in compliance with a legacy frame structure, for example,using a legacy frame structure for EDMG Beacon and/or SSW frames, e.g.,as described below.

In some demonstrative embodiments, including an EDMG support indicationin a frame having a legacy frame structure, may enable to signal theEDMG capability indication in a backwards compatible fashion, e.g., evenwithout requiring a STA to perform BF with an AP/PCP STA to exchangeprobe frames, and to discover that EDMG is not supported.

In some demonstrative embodiments, communicating the indication of thecapability of a STA to support EDMG features according to a legacy framestructure may be advantageous, for example, at least by enablingbackwards compatibility, e.g., in an efficient manner, for example, bynot requiring an additional overhead in DMG Beacon frames and/or DMG SSWframes, and/or by not requiring STAs to perform BF, e.g., prior todiscovering if a STA have EDMG capabilities.

For example, in addition to the defining of an EDMG capability IE, theEDMG support indication may also be signaled in the existing legacyframe structure. Such a solution may obviate a need to require a STA toperform BF and exchange probe frames, e.g., only to discover that thecapability is not supported.

In some demonstrative embodiments, at least one EDMG capability field,for example, an EDMG support field (“EDMG Supported field”), e.g., a 1bit field, may be defined as part of at least one type of framestructure according to a legacy frame structure, e.g., as describedbelow.

In other embodiments, the EDMG capability field may be defined and/orincluded as part of one or more additional and/or alternative types oflegacy frame structures.

In other embodiments, one or more additional or alternative types ofEDMG capability fields, e.g., having one bit or any other number ofbits, may be defined and/or included in a legacy frame structure, e.g.,in addition to or instead of the 1-bit EDMG Supported field.

In some demonstrative embodiments, devices 102 and/or 140 may beconfigured to communicate an indication of a capability of a STA, e.g.,implemented by devices 102 and/or 140, to support EDMG features, e.g.,according to an IEEE 802.11ay Specification, as part of a frame having astructure in accordance with a legacy frame structure, e.g., a framestructure according to an IEEE 802.11ad Specification.

For example, the EDMG wireless station, e.g., theSTA implemented by device 140 and/or the STA implemented by device 102,may select not to communicate an EDMG communication with the peerwireless station, for example, if a frame from the peer wireless stationdoes not include the EDMG supported field with the bit value of 1.

Referring back to FIG. 1, In some demonstrative embodiments, a firstEDMG STA, for example, a first STA implemented by a first device ofdevices 102 and/or 140, may be configured to generate and transmit aframe, for example, a frame compatible with a legacy frame structure,including a field, e.g., DMG parameters field 300 (FIG. 3), beaconinterval control field 400 (FIG. 4), SSW feedback field 500, and/or anyother field, including an EDMG supported field, e.g., EDMG supportedfield 310 (FIG. 3), EDMG supported field 410 (FIG. 4), EDMG supportedfield 510 (FIG. 5), and/or any other EDMG supported field, set toindicate that the first EDMG STA supports EDMG features.

The EDMG STA may be configured tomake a decision as to whether to proceed and perform BF with the PCP/APSTA. For example, if the EDMG STA determines that EDMG features are notsupported by the PCP/AP STA, the EDMG STA may decide not to join a BSSof the PCP/AP STA, for example, even before performing BF with thePCP/AP STA.
